Adding a candidate node to a cluster

You can add an IBMTSSVC_CandidateNode to an existing IBMTSSVC_Cluster.

1. Obtain the reference (CIMObjectPath) of the IBMTSSVC_Cluster to which you want to add an IBMTSSVC_CandidateNode.
2. Obtain the Reference for the IBMTSSVC_CandidateNode instance.
3. Locate the IBMTSSVC_ClusteringService instance that is associated with the IBMTSSVC_Cluster by traversing the IBMTSSVC_ClusteringServiceForSystem association.
4. Invoke the IBMTSSVC_ClusteringService.AddNode() method. The AddNode method has the parameter CandidateNode Ref, and the IOGroup Ref to which you want to add the Node. Every node must be in an IOGroup and each IOGroup can only contain two nodes.
